The lower end of the passage I56 connects with the upper end of thepassage I5? in the cock castlog it, the lower end of which passage E5?in turn opens into the barrel l I4 at a point diametrically opposite tothe passage Ml.

Formed upon the cock casting lilo is a horizontal tubular member I58,the inner end of which communicates with the barrel IN at a point in thepath of movement of the ports I40 and ii.

To the outer end of the tubular member E58, is. connected, by unions l53and I60, a pipe lot, the union I60 being provided with a valve E52, bywhich the rate at which fluid passes through the union may becontrolled.

Formed in the cock barrel H4, at a point diametrically opposite to themember i513 is a perforation I63 which establishes aconnection betweenthe inner end of the aforesaid passage l5i,

' and the inside of the said barrel, a needle valve I64 being screwedinto the bush I52, by means of which valve the efiected area of the'saidperforation may be adjusted.

Provided within the passage I21, beneath a manhole, fitted with ascrewed plug I65, is a valve I68, shown in interrupted lines in Fig. .7,by which valve the rate of flow of fluid along the pipe I00 may beregulated.

When the cock barrel plug H5 is in the position in which it is shown inFigs. 7, 8 and 9, liquid passes into the apparatus by the pipe I3I,passages I20, I30 and I42, thence through port I30, chamber I36, portI30 and I45 into the casing 03. i

v The liquid then passes through the filter cloth I03, the perforationsof the walls of the cylinder I02, the perforated upper end of the drum00, and

downwardly through the layer of softening agent 8|. v

The softened water, after leaving the layer passes through the layer ofgravel 32, then out through the perforated bottom wall of the drum 00into the casting 00.

From the casting 00, the softenedwater passes through passages 00, 00,pipe I00, passages I21,

I28 and I43, thence through port I40, chamber I31 port I4I, unions I50,I60 and, finally, out through pipe I3I.

When it is desired to reactivate the softenin agent the cock barrel II3is turned into the position shown in Figs, and 16 (its second position)which cuts off the supply of liquid from the pipe I3I and causes theplate I20 to drop in order to permit ready access to the handles H3.

The spindle I00 is then unscrewed, and, after the transverse member I I0has been swung clear,

the lid I00 is swung open upon its pivot I00a.

Itis to be noted that the turnin of the barrel IIi into the positionjust described permits any liquid within the container I01 to drainthrough a perforation I561: into the passage I50, through port I30,chamber I33, port I30, passages'I43, I40 and.l50,'into the'passage IOIand bush I52,

v whence it flows out through branch I53 and pipe I54.

passages I41, I44 and The container I01 is then filled withsalt, afterwhich the lid I00 is carefully replaced and fixed correctly in position.

The cock barrel H5 is then rotated into its third position in which itis shown in Figs. 17 and 18, and this permits liquid from passages-I42,I30, I20 and pipe I3I to pass through port I30, chamber I33, port I30,passages I01 and IE0, into the container I01 where it mixes with anddissolves gravel 32, and through the perforated bottom wall of the saiddrum, into the casting 00..

The solution leaves the casting 30 by way of passages 03, 09 nd pipeI00, from which latter it passes through passages I21, I20, I43, thenceby way of port I, chamber I31. P rt I and opening I63, into passage I5Iand bush I52, and, finally, out through branch- I53 and pipe I04.

Provided within the casing 00 are strips such as 06a, carrying bristles00b which engage with the filter cloth I03, in order that when thefiltering and softening assembly is rotated with the ring 03, bytwisting the spindle 03, any deposit upon the outer: surface of thefilter cloth may 4 or drained through be brushed off and flushed thedrain cock 02.

Having now particularly described and ascertained the nature of my saidinvention, and in what manner the same is to be performed, I declarethat what I claim'is: 1

1. Water treating apparatus comprising a treating chamber, a waterinlet, a treated water outlet and a waste water outlet, means to permitthe introduction of a regenerating substance, and a plug andbarrel cockthrough which water passes, connections between said cock barrel andsaid chamber, inlet, outlets and means, characterized in the plug isprovided with two axially in line chambers, each chamber being closed atits ends and having two ports angularly displaced and arranged tocooperate with said barrel connections, in one position of'the cock plugto pass water from the inlet to the treated water outlet,

through the treating chamber, in another position to close the waterinlet and outlets and to permit the introduction through said means of aregenerating substance, and in a third position, to pass water from theinlet to the waste water outlet, through the treating chamber, the waterin passing to the treating chamber, entraining the regeneratingsubstance and in said first and third positions, the ports of eachchamber being alternately employed as inlet and outlet ports, everyother position of the plug in its rotation closing the apparatus toprevent the passage of .water therethrough.
